A clear increase in ectopic PAL-1 was observed in the distal germline of
mex-3(RNAi);
gld-1(RNAi) worms. In 100% of
gld-1 (
q485) and RNAi worms, between 0-50 distal germline nuclei express PAL-1 (n=63), whereas in 71% of
gld-1(RNAi);
mex-3(RNAi) worms, between 50-200+ distal germline nuclei express PAL-1 (n=41). Hence, in wild-type worms,
gld-1 inhibits both PAL-1 and MEX-3 expression in the distal germline, while MEX-3 inhibits PAL-1 expression in the proximal germline.
